Any way many congratulations. BTW, how do you manager the locking testing, I am just at this step and would like to find out your lost points with you.

I actually do not know where i lost points. I was thinking that testing it with few threads runnings long transactions is the way. I wrote a test class that would spawn 25 threads and in each thread it will perform some random transactions. I tested it rigorously but still i did not get full marks. So i think you should better ask someone else who would have got full marks in this

I had placed combo boxes for the Hotel and City Names. With each hit to the Middle tier i used to return meta data that is nothing but the list of hotels and cities that would be refreshed in the UI.

I also had two buttons one for Booking and one for Searching. For search results there were two filters (checkbox) one for within 48 hours and another for only unbooked rooms. Anothe checkbox would allow OR search and by default it would do an AND search.

I do not know how to upload a pic else i would have done that.

Thank you Mark Chulwoo and all others. I needed advice from you guys. What should be the next step? Swing and JAva Standalone are challenged by AJAX these days. How far would having a profile of a Swing developer take me?

Just out of curiosity, when did you take the written exam and how long did it take to get your results? I sat the exam on the 4th so I am waiting impatiently for my results, I don't expect them until Feburary at the earliest.
